BMI Formula Explained
The calculator uses the standard BMI formula recognized worldwide.
BMI Formula
BMI=Height(m)2Weight(kg)
Where:
- Weight is measured in kilograms
- Height is measured in meters
How the Formula Works
The formula divides body weight by the square of height.
For example:
A woman who weighs 65 kg and has a height of 1.65 meters would calculate BMI as:
BMI=(1.65)265
Result:
BMI = 23.88
This falls within the Normal Weight category.
BMI Categories for Women
The calculator classifies BMI into standard categories.
| BMI Range | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal Weight |
| 25 – 29.9 | Overweight |
| 30 and Above | Obese |
Understanding Each BMI Category
Underweight (BMI Below 18.5)
Being underweight may indicate:
- Nutritional deficiencies
- Low energy reserves
- Weak immune system
- Hormonal imbalance
Women in this range may need to improve nutrition and consult healthcare professionals if necessary.
Normal Weight (BMI 18.5–24.9)
This range is generally considered healthy.
Benefits often include:
- Lower disease risk
- Better mobility
- Improved heart health
- Balanced energy levels
Women within this range are encouraged to maintain healthy habits.
Overweight (BMI 25–29.9)
This range may increase the risk of:

Lifestyle adjustments like exercise and balanced nutrition may help.

Healthy Weight Range Explained
The calculator also provides a healthy weight range based on your height.
The healthy range is calculated using BMI values between:
- 18.5 (minimum healthy BMI)
- 24.9 (maximum healthy BMI)
Healthy Weight Formula
Minimum Healthy Weight
Minimum Weight=18.5×Height2
Maximum Healthy Weight
Maximum Weight=24.9×Height2
This helps women understand their recommended weight range for optimal health.
Example BMI Calculation
Let’s calculate BMI using a practical example.
Example Data

Step 1: Convert Height to Meters
168 cm = 1.68 meters
Step 2: Square the Height
1.68 × 1.68 = 2.8224
Step 3: Apply BMI Formula
BMI=2.822470
BMI = 24.8
Step 4: Interpret Result
BMI Category:
